Psychological treatments for epilepsy

Non-pharmacological treatments for pediatric refractory epilepsies

INTRODUCTION

Antiseizure medications (ASMs) are the primary treatment option for epilepsies of wide etiologies, however, about 10-20% of children do not gain sustained seizure control and in this case, it is worth investigating "alternative" therapeutic approaches aside from ASMs. Nowadays, non-pharmacological strategies for epilepsy treatment encompass dietary interventions, neurostimulation-based techniques, and biobehavioral approaches.

AREAS COVERED

A search on PubMed database was conducted. Experimental and clinical studies, as well as meta-analysis and structured reviews on the latest non-pharmacological treatments for drug-resistant epilepsy (DRE) in children, were included. Special attention is given to the efficacy and tolerability outcomes, trying to infer the role novel approaches may have in the future.

EXPERT OPINION

The large heterogeneity of primary clinical outcomes and the unavoidable subjective response of each patient to treatments prevents Researchers from the identification of a single, reliable, approach to treat DRE. The understanding of fine pathophysiologic processes is giving the way to the use of alternative therapies, such as the well-known ketogenic diet, in a "personalized" view of treatment. The goal is to apply the non-pharmacological treatment most suitable for the patient's sake.

What really matters? A mixed methods study of treatment preferences and priorities among people with epilepsy in the UK

The widening range of treatment options for epilepsy, and their potential outcomes, mean decisions about treatment for people with epilepsy (PWE) are often complex. While antiepileptic drugs (AEDs) represent the mainstay of treatment, other potential nondrug interventions are gaining in importance. These treatments all have the potential for harming those using them, as well as bringing benefits. This study examined the views and experiences of PWE about a range of treatment options. We used both qualitative and quantitative approaches - a series of depth-narrative interviews, followed by a large-scale survey. Treatment options and healthcare priorities deemed important by at least 10% of interview participants were then addressed as a series of statements in the follow-on survey questionnaire. Quantitative responses supported healthcare priorities identified through the qualitative interviews. The key goal of treatment among study participants was to be able to live 'a normal life'. Important physical, psychological, and life benefits of treatment were identified - most being the direct consequence of improved seizure control. One psychological benefit, reduced worry, was also identified as an important treatment goal. All participants viewed AEDs as appropriate first-line treatment; and since adverse effects of AEDs had implications for individual levels of daily function and wellbeing, their appropriate management was considered important. In contrast, surgery was almost always regarded as the treatment of last resort. Despite lack of research evidence supporting their use, participants were interested in complementary therapies as adjunctive treatment and a means of coping with having epilepsy, with yoga and meditation of particular interest. An important finding was the desire for targeted services to help with memory problems, as was the call to increase availability of psychological/counseling services. Our findings emphasize the importance of providing treatment responsive to the life context of individual patients. They highlight not only the level of demand for specific treatment options, but also the need for high-quality evidence to support future investment in their provision.

Can an epilepsy nurse specialist-led self-management intervention reduce attendance at emergency departments and promote well-being for people with severe epilepsy? A non-randomised trial with a nested qualitative phase

Objectives

To (1) describe the characteristics and service use of people with established epilepsy (PWE) who attend the emergency department (ED); (2) evaluate the economic impact of PWE who attend the ED; (3) determine the effectiveness and cost-effectiveness of an epilepsy nurse specialist (ENS)-led self-management intervention plus treatment as usual (TAU) compared with TAU alone in reducing ED use and promoting well-being; (4) describe patients' views of the intervention; and (5) explore their reasons for attending the ED.

Design

Non-randomised trial with nested qualitative study.

Setting

The EDs of three inner London hospitals. The EDs each offer similar services and support a similar local population, which made a comparison of patient outcomes reasonable.

Participants

Adults diagnosed with epilepsy for ≥ 1 year were prospectively identified from the EDs by presenting symptom/discharge diagnosis. We recruited 85 of 315 patients with 44 forming the intervention group and 41 the comparison group.

Intervention

Intervention participants were offered two one-to-one outpatient sessions delivered by an ENS who aimed to optimise self-management skills and knowledge of appropriate emergency service use. The first session lasted for 45–60 minutes and the second for 30 minutes.

Main outcome measures

The primary outcome was the number of ED visits that participants reported making over the 6 months preceding the 12-month follow-up. Secondary outcomes were visits reported at the 6-month follow-up and scores on psychosocial measures.

Results

In the year preceding recruitment, the 85 participants together made 270 ED visits. The frequency of their visits was positively skewed, with 61% having attended multiple times. The mean number of visits per participant was 3.1 [standard deviation (SD) 3.6] and the median was two (interquartile range 1–4). Mean patient service cost was £2355 (SD £2455). Compared with findings in the general epilepsy population, participants experienced more seizures and had greater anxiety, lower epilepsy knowledge and greater perceived stigma. Their outpatient care was, however, consistent with National Institute for Health and Clinical Excellence recommendations. In total, 81% of participants were retained at the 6- and 12-month follow-ups, and 80% of participants offered the intervention attended. Using intention-to-treat analyses, including those adjusted for baseline differences, we found no significant effect of the intervention on ED use at the 6-month follow-up [adjusted incidence rate ratio (IRR) 1.75, 95% confidence interval (CI) 0.93 to 3.28] or the 12-month follow-up (adjusted IRR 1.92, 95% CI 0.68 to 5.41), nor on any psychosocial outcomes. Because they spent less time as inpatients, however, the average service cost of intervention participants over follow-up was less than that of TAU participants (adjusted difference £558, 95% CI –£2409 to £648). Lower confidence in managing epilepsy and more felt stigma at baseline best predicted more ED visits over follow-up. Interviews revealed that patients generally attended because they had no family, friend or colleague nearby who had the confidence to manage a seizure. Most participants receiving the intervention valued it, including being given information on epilepsy and an opportunity to talk about their feelings. Those reporting most ED use at baseline perceived the most benefit.

Conclusions

At baseline, > 60% of participants who had attended an ED in the previous year had reattended in the same year. In total, 50% of their health service costs were accounted for by ED use and admissions. Low confidence in their ability to manage their epilepsy and a greater sense of stigma predicted frequent attendance. The intervention did not lead to a reduction in ED use but did not cost more, partly because those receiving the intervention had shorter average hospital stays. The most common reason reported by PWE for attending an ED was the lack of someone nearby with sufficient experience of managing a seizure. Those who attended an ED frequently and received the intervention were more likely to report that the intervention helped them. Our findings on predictors of ED use clarify what causes ED use and suggest that future interventions might focus more on patients' perceptions of stigma and on their confidence in managing epilepsy. If addressed, ED visits might be reduced and efficiency savings generated.

Distance delivery of mindfulness-based cognitive therapy for depression: project UPLIFT

This study evaluated the efficacy of a newly developed, home-based depression intervention for people with epilepsy. Based on mindfulness-based cognitive therapy (MBCT), the eight-session, weekly intervention was designed for group delivery via the Internet or telephone. Forty participants were randomly assigned to intervention or waitlist. Depressive symptoms and other outcomes were measured at baseline, after intervening in the intervention group (~8 weeks), and after intervening in the waitlist group (~16 weeks). Depressive symptoms decreased significantly more in the intervention group than the waitlist group; Internet and telephone did not differ. This effect persisted over the 8 weeks when those waitlisted received the intervention. Knowledge/skills increased significantly more in the intervention than the waitlist group. All other changes, though not significant, were in the expected direction. Findings indicate that distance delivery of group MBCT can be effective in reducing symptoms of depression in people with epilepsy. Directions for future research are proposed.

The relationships among medicine symptom distress, self-efficacy, patient-provider relationship, and medication compliance in patients with epilepsy

The purpose of this study was to investigate the relationships among medicine symptom distress, self-efficacy, patient-provider relationship, and medication compliance in patients with epilepsy. Patients with epilepsy (n=357) were recruited using convenience sampling from three medical centers in northern Taiwan. Results showed significant differences in relationships between medication compliance and the following factors: gender, employment status, comorbid chronic diseases, self-driving, daily drug dosing frequency, seizure after a missed dose, and self-efficacy. Logistic regression analysis indicated that comorbid chronic disease, self-driving, seizure after a missed dose, and self-efficacy were significantly associated with medication compliance. These data suggest that health care providers of patients with epilepsy pay more attention to treatment of comorbid chronic diseases, the safety issues of self-driving, seizures occurring after missed doses, and awareness of self-efficacy.

UK self-care support initiatives for older patients with long-term conditions: a review

OBJECTIVES

Supporting self-care for people with long-term conditions is an aim of UK health policy. As many with long-term conditions are older it is of interest to explore which self-care support interventions have positive impacts for this group. This review explores what types of intervention have been reported in the UK and their impact upon older people.

METHODS

Studies were identified using existing reviews, electronic databases and through hand searching journals. After inclusion and exclusion criteria were applied data were extracted from 18 studies. These were summarized in a narrative synthesis supported by summary tables.

RESULTS

All studies described interventions to support self-care, many targeted at people with arthritis. All used patient education, usually delivered to groups by a range of professionals. The majority of studies reported some significant positive outcomes, most frequently changes in physical functioning, illness knowledge and increased self-efficacy. The average age of participants was 60.

DISCUSSION

This review shows that self-care interventions have had positive effects for older participants but it remains unknown how best to support self-care in participants over 75, a group of people with long-term conditions who may have different needs.

Alternative approaches to conventional antiepileptic drugs in the management of paediatric epilepsy

Over the last two decades, there has been a rapid expansion in the number and types of available antiepileptic drugs (AEDs), but there is increasing concern amongst parents and carers about their unwanted side effects. Seizure control is achieved in approximately 75% of children treated with conventional AEDs, but non-conventional (or non-standard) medical treatments, surgical procedures, dietary approaches, and other non-pharmacological treatment approaches may have a role to play in those with intractable seizures or AED toxicity. Many of the approaches are largely common sense and are already incorporated into our current practice, including, for example, avoidance techniques and lifestyle advice, while others require further investigation or appear to be impractical in children.
